IMPROVEMENTV IN .i WATER-ELE/ATORS.

Specification forming part of Lettcrsdatent No. 40,374, dated October 20, 1863.

To all whom it may concern:

Be it kncwn that I, THOMAS J WADLEIGH, of Sutton, in the county of Merrimack and State of New Hampshire, have inventedla newv and Improved Water-Elevator; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, makinga part of this specification, in which- Figure 1 is avertical section of myinvention, taken in the linea1 Fig. 2; Fig. 2, a vertical section of the same, taken in the line y y, Fig. 1; Fig. 3, avertical section of both drums and the looking device, showing the operation of the automatic locking device; x, Fig. 2, indicate the plane of section; Fig. 4, a diminished end view of the shaft of the windlass, with pawl and ratchet.

Similar letters of reference indicate correspondin g parts in the several figures.

Thisinvention consists in the employment or use of a windlass provided with two loose drums, to each of which a bucket is attached by a rope or chain, said drums being provided each with a gear, into which a pinion meshes or engages, and also provided each with a a lever, the above parts being used in connection with a locking device,and all arranged in such a manner that by a continuous movement or rotation of the windlass in one direction the buckets may be raised and lowered, the two buckets moving in opposite directionsthat is to say, one being raised while the other is loweredand the iilled bucket, as it reaches its highest or culminating point, tilted and deprived of its contents.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a well-curb, which may be of rectangular or any suitable form, and having a shaft, B, on its upper part,'provided with a crank, C at onev end. On this shaft B there are placed loosely two drums, O C, each of which has a gear, D, at its inner end, andinto these gears D a pinion, E, meshes, said pinion having its shaft a fitted in a crossbar, b, of the curb A. Each drum C has a spiral groove, o, made in it, the groove of one drum having a right-hand and the other a left-hand pitch, so that both advance toward the center of the windlass, and each drum has arope or chaimd, attached to it near its outer end,`said ropes or chains winding upon the drums or unwindin g therefrom in the grooves c, as will be fully understood by referring to Fig. 1. Each rope or chain d has a bucket, F, attached to its end.

On the shaft B, between the two drums G (l, there is permanently secured a clip, G, in which a button or plate, H, is secured by a pivot, e. 3.) This button or plate is allowed to work freely on its pivot e, and it is of such awidth that when turned either to the right or left its ends will come in contact with the inner ends ofthe drum C, which are made in spiral form or have recesses cut in them, so as to cause them to have a shoulder or projection, f, against which the ends ofthe button or plate H catch and which connects the drums with the shaft B or causes the former to rotate with the latter. Each drum G has a lever, I, fitted in itlongitudinally, with asprin g, g, bearing against its inner side and nearits outer end and the inner ends of these levers project beyond the inner ends of the drums, the springs g having a tendency to keep the inner ends of the levers in contact with shaft B, and behind the button or plate H, and not in contact with it. The outer ends of the levers I project out from the periphery of the drums (l, and are each provided with a friction-roller h. These friction-rollers are in line with the inner parts of the spiral grooves c.

J represents the water-discharge spout, which is placed in an inclined position at one side of the curb A, and has two hooks, K K, attached to it, which are in line with the paths of the buckets F and extend upward a short distance above the spout J.

The operation is as follows: As the shaft B is rotated, one end of the button or palateH will be in contact with the shoulder or projection fat the inner end of one of the drums, C, and said drum will in consequence be rotated with the shaft B, and the bucket F will be elevated until its upper edge comes in contact with the hook K, which is in line with it, and the eleA vated bucket will be tilted and its contents discharged into the spout J. At this time the rope or chain of the elevated bucket will have pressed inward the outer end ofthe lever I, in consequence of said rope or chain winding over said lever, and when the latter is thus (See more particularly Figs. l and' moved it turns the button or plate H out of contact with the projection fof the drum of the elevated bucket and within the path of the projection j' of the other drum, thereby causing the latter to rotate with the shaft B, while the drum of the elevated bueketwill be free from the shaft and will receive through the medium of the gearing a motion reverse to that of the shaft. Hence the l,elevated and empty bucket will be lowered, while the other, which is at the bottom of the well and filled, will be raised and when fully elevated will be tilted, in consequence of coming in contact with its hook K, and its contents discharged into spout J, said bucket being lowered in turn in consequence of the lever I of its drum actuating the button and plate H, so as to disconnect the drum of the elevated bucket from the shaft B and connect the drum of the lowest bucket to the shaft. Thus it will be seen that by a continuous rotation of the shaft B in one direction the buckets F will be alternately raised and lowered, and by an entirely automatic mechanism. The llevers 1, it will be seen, are actuated so as to move the button or plate H, in consequence of the ropes or chains d pressing on the outer ends of said levers, as the buckets reach their culminating paints and insure a perfect action of these levers. The inner parts of the groove c are spread inward, as shown at a* in Fig. 1, to' bring the ropes Vor chains over the inner ends of said levers and cause them to be operated with certainty.

I would remark that the shaft B may be retained at any desired point by a pawl and ratchet.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The two drums O G, placed loosely on .the shaft B, connected by gears, as shown, and provided with levers I I, in combination with the locking device for alternately connecting the drums tothe shaft, the same consisting of the pivoted button and plate H and the shoulders or projection fat the inner ends of the drums.

2. The particular manner of operating the levers I to unlock or detach the drums from the shaft B-to wit, by means of the spiral grooves c o in the drums U, with the ropes or chains d working therein, substantially as described.
